On the program, he said his eyebrows didn’t show up very well on screen, and he had concerns over them. He even went on to admit he had an eyebrow procedure in which parts of the eyebrows are tattooed to make it look as if they were real.

He had the procedure to look like Song Seung Heon’s caterpillar eyebrows. However, due to his mother’s greed, Kang Sung Jin’s eyebrow procedure was overcompensated, and instead looked like a bushy mess.

Kang Sung Jin also talked about how he commandeers his mother-in-law’s bed whenever he and his wife go to visit, drawing many gasps from the other show guests.
